CORNER CONTACT MEMBER FOR WEATHER STRIPS Filed Oct. 25, 1928 2 Sheets-Sheet 2 lama iii 7 0121; 11 666 Patented Oct. 29, 1929 UNHTED STATES PATENT orrics FRANK REESE, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO REESE METAL WEATHER STRIP CO.. 015 MINNEAPOLIS, MINNESOTA, A CORPORATION 03 MINNESOTA CORNER CONTACT MEMBER FOR WEATHER STRIPS Application filed October 26, 1928.

My present invention relates to weatherstrips for double-hung windows and has for its object to provide corner contact members for sealing the open space between the frame and sill Weatherstrip members.

To the above end, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which il lustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a fragmentary perspective view of the frame and lower sash of a doublehung window having the invention applied thereto;

Fig. 2 is a view partly in outside elevation and partly in vertical section taken on the irregular line 22 of Fig. 1;

Fig. 3 is a view in horizontal section taken on the irregular line 3-3 of Fig. l; and

Fig. l is a vertical section taken on the line H of Fig. 3.

In the drawing there is illustrated the frame 5 and lower sash of a doublehung window. lVeatherstrips for the sash 6 include frame members 7 and sash members 8 which have sliding interlocking engagement the one with the other. Said weathcrstrips further include a sill member 9 which er;- tends the full length of the window sill between the sides of the frame 5. This sill member 9 is arranged to enter, with wiping contact, a longitudinally extended groove 10 in the under side of the lower member of the sash 6 when said sash is closed and form a weather-tight joint therewith.

From a broad point of view, the weatherstrip members 7, 8 and 9 may take various different forms. The corner contact member 11, which is the subject matter of the present application, is provided to seal the space or opening between the frame and sill Weatherstrip members 7 and 9, respectively, to reduce the leakage of air therebetween to a minimum. As shown, there is one of these corner contact members 11 in each corner of the frame 5 at the sill thereof and a complete installation for a double-hung win- Serial No. 315,282.

dow will further include two of these corner contact members 11 in the upper corners of the frame 5 for the upper sash, not shown. For the purpose of this case it is not thought necessary to illustrate these upper corner contact members as they are substantially identical with the lower corner contact members. I 7

Each corner contact member 11, as shown, is in the form of a relatively wide flat spring, the upper end of which is secured by nails 12 to the frame 5. The lower or free end portion of the corner contact 11 extends ob liquely from the frame 5 into the path of movement of the lower sash 6 to be engaged thereby during its closing movement.

During the closing movement of the lower sash 6, the two lower contact members 11 are engaged thereby and yieldingly pressed toward the sides of the frame 5 to form a tight joint between said frame and sash and between the frame members 7 and sill member 9. These corner contact members 11, at their lower end portions, are bifurcated at 13 to receive the respective end portions of the sill member 9 with freedom for springing movement longitudinally thereof. Said cor,- ner contact members 11 extend into close contact with the frame members 7 and sill mem her 9 and thereby close or seal the opening between said members.

The lower contact members 11 also, by their spring action, center the sash 6 in the frame 5 so that the lower horizontal member of the sash 6 comes into direct contact with the window sill throughout its entire length and thereby causes a more perfect contact between the sill member 9 and sash 6 where said member enters the groove 10 in said sash.

The corner contact members 11 are symmetrical so that they may be used in either right or left-hand corners.

hat I claim is:

1. The combination with a frame and a sash slidably mounted therein, of spring corner contact members between the frame and sash and forming Weatherstrip sections which extend transversely of the sash.

2. The combination with a frame and a sash slidably mounted therein, of spring corner contact members between the frame and sash.

3. The combination with a frame and a sash slidably mounted therein, of spring corner contact members on the frame arranged to be engaged by the sash during its closing movement for centering the sash and be held thereby compressed between the frame and sash.

4. The combination with a frame and a sash slidably mounted therein, of weatherstrips comprising a frame member and a 00 operating sash member, a sill member laterally spaced from the frame member and with which the sash interlocks when closed, and a corner contact member closing the gap between said frame member and sill member.

5. The combination with a frame and a sash member slidably mounted therein, of weatherstrips comprising frame members and co-operating sash members, a sill member laterally spaced from the frame memher, and with which the sash interlocks when closed, and corner contact members between said framemembersand sill member closing the. gaps.

6. The structure defined in claim!) in which the corner contact members are in the form of flat springs arranged to be held by the sash when closed compressed between the frame and sash.

7. The structure defined in claim 5 in which the corner contact-members are in the form of fiat springs arranged to center the sash when closed and be held thereby compressed between the frame and sash.

8.. The combination with a frame and a sash slidably mounted therein, of weatherstrips comprising frame members and cooperating sash members, a sill member laterally spaced from the frame members and with which the sash interlocks when closed, and corner contacts closing the gaps between said frame members and sill member, said corner contact members being in the form of flat springs secured to the frame and extending'in the path of movement of'the sash to be engaged thereby duringits closing movement to be held compressed between theframe and sash.

9 The structure definedin clai-m-8 in which the sill member is laterally spaced from the frame members and in which the corner con? tact members are bifurcated to receive the sill member.

In testimony whereof I affix my signature.
